Gwen Stacy (Earth 5398) Undead Ghost

I am Gwen Stacy from Earth 5398 and I am 24 years old. When I was 18 years old, I was diagnosed with an incurable disease, and my boyfriend, Peter Parker, was working on a medicine to cure me that used the DNA of a radioactive spider. The medicine was made, but my body did not match with the medicine and it had very bad effects on my body to the extent that I went into a coma and there was a possibility of my death at any moment. One of Peter's old colleagues, Professor Reid Richards, used cosmic rays to treat me and I was cured. But I was in a coma until I was 22 years old. When I came to my senses, I realized that 1 year ago my whole family was Died in the Infinity War and Peter was killed by Thanos. I was depressed for 8 months and decided to commit suicide. I went to the top of the oscorp tower and threw myself down. I didn't die after hitting the ground and survived without any injuries! I realized that the cosmic rays caused me to gain supernatural powers. I tried to kill myself many times, but I couldn't! I was very angry! I had no family! I had no reason to live! I went out of rage and killed Reed Richards and all the members of the Fantastic 4! I was no longer in control! Killing was fun for me! It happened that I became a murderer and I would kill anyone for money! I had high strength, speed and intelligence and I could change the shape of my body and melt everything with my hands! This is how I became to Undead Ghost!
